Abstract: The article presents the results of studies of the gross content and non-bonded compounds of manganese and zinc in calcic chernozem of ampelocenosis. The investigated trace elements are characterised by accumulative type of profile distribution with the greatest accumulation in the humus-accumulative layer. The stocks of trace elements in the metre layer of soil were calculated. The share of exchangeable Zn from its total content in the profile of calcic chernozem is low - from 0.30 to 0.42%, for Mn - from 2.54 to 2.86%. In the upper horizons the percentage of exchangeable compounds of the studied trace elements from the sum of their complex and specific sorbed ones is 15 - 32%. A strong correlation between the content of exchangeable compounds of the studied trace elements, humus (r=0.77-0.92) and CaCO3 (r=-0.78-0.96) was found.
